You, Katsuki Tonikawa a normal high school student suddenly got transported into a strange hall along with your classmates. You are surrounded by a bunch of people wearing robes. Each of them are holding an appraisal orb, as they appraise everyone's magical talents you are the last one to be appraised. But with a cruel twist of faith, you end up the only one unable to conjure up magic. With no time to think the robed people uncover something that looks like big rock, they call it the "Creation artifact" said to create anything the user desires but the items created will not contain any magical properties. You'll have to think this through on what weapon or piece of equipment you need. And after this you'll have to come up with ingenious exploits in order to survive.
